2 ohm Bass Heads

Hey guys Shane here I was wondering if anyone could throw some 2 ohm bass heads that are mainly rated at the 500W range!! If anyone could help a brotha out it would mean a lot.. I'm looking for something that has a good tone of course.

Genz NeoPak 3.5 is 350 at 4 ohms and 500 at 2 ohms, most all EA heads (older iAmps or the newer Micros, Doublers and the Pro). Carvin stuff, a lot of Ampeg's gear, Mesa Walkabout and most of their stuff. Fair amount of options! There's always the pre/power rig too
